Cauline leaves shortly petiolate; blade (often lanceolate, reduced in size distally), base tapered or cuneate, not auriculate, (apex acute). Racemes paniculately branched. Fruiting pedicels spreading to divaricately ascending, (slender), (5–) 10–15 (–25) mm. Flowers: sepals 3–8 × 1–1.7 mm; petals pale-yellow, narrowly obovate, 7–15 × 3–4 mm, claw 2–3 mm, apex rounded; filaments 3–6 mm; anthers 1.5–2 mm; gynophore 1–1.5 mm in fruit. Fruits (stipitate), spreading to divaricately ascending, strongly torulose, linear, subcylindric, 1.5–3 cm × 1.5–2 mm; valvular segment with 5–13 seeds per locule, 1.2–2.5 cm, terminal segment seedless or 1-seeded, (conic), 3–6 mm. Seeds brown or yellow, 0.6–1.2 mm diam.; seed-coat finely reticulate-alveolate, not mucilaginous when wetted. 2n = 16.
